Question

Quizplus · Accepted Answer

The recombination frequency is calculated as the number of recombinant offspring divided by the total number of offspring. Recombinant offspring are those that have a combination of traits not seen in either parent, which in this case are the 100 blue, long and 100 white, short. So, the calculation is 200 (100 blue, long + 100 white, short) divided by 1000 (total offspring), which equals 0.20 or 20%.
